Gabal Gattar area is situated in the northern Eastern Desert of Egypt, SW Hurghada city and is considered as an area of high potentialities for uranium deposits. The area is covered by Hammamat sediments and Gattarian granites. The Hammamat sediments are dissected by different types of dykes, while Gabal Gattar granites are cut only by basic dykes. These granites are mentioned as the younger pink granites, perthitic leucogranites, calc-alkaline and within plate granites. The granitic rocks are considered as one of the most essential sources for uranium deposits. The structural deformations of the study area are represented by primary structures and secondary ones. The most prevailing structures are folding, faulting and jointing. The faults, especially those trending in the NNE-SSW and N-S directions played as passways to the ascending uranium-bearing hydrothermal solutions carrying uranium mineralizations. Most of them are located within a large pull apart basin. It is found from the relation between structures and uranium mineralization within the highly promissing shear zones that uranium mineralizations are located within a large pull-apart basin, having about 2 km length and 0.5 Km width. Delineation and evaluation of mineral resources are most important exploration parameters required for investment decisions. Identifying the best probable sites for uranium mineralization in terrains of lack subsurface penetrations is a challenging task. In northern part of Egyptian Eastern Desert, the uranium occurrences of Gabal Gattar area are among the most important source of uranium mineralization. The famous uranium mineralization in this occurrence is restricted to the geological contact zone between the Hammamat sedimentary rocks and the G. Gattar Alkali feldspar granite. As well, molybdenite-rich granite samples were collected from Gabal Gattar granitic pluton which represents one of the most important molybdenum mineralized district in Egypt. The Gabal Gattar area has been investigated for uranium by the Nuclear Materials Authority of Egypt (NMA) with the exploration program which was created in 1984. G. Gattar area locates in the high mountainous terrains of the North Eastern Desert of Egypt (Fig. 1). The exploration efforts, carried out by the NMA at G. Gattar area, led to the discovery of more than twenty uranium occurrences in the northern parts of G. Gattar granite (Shalaby, 1990, 1996; Abu Zaid, 1995; El Zalaky, 2002; El Kholy el al., 2012). These occurrences were named, according to date of discovery as, G-I, G-II, G-III, G-IV, G-V…etc. (Fig. 2).
